Deprecate Aqua about qiskit-aqua HOT 2 CLOSED

FWIW, I don't think it's worth deleting anything from the aqua repo. I think a better post deprecation period plan (since we're deprecating pretty much everything) is to just archive the entire aqua repostiory after the last release at the end of the deprecation period.

By deletion I was really only considering code that we stated was deprecated and would be removed after 0.8; we did not get around to doing that and normally we would have done this so that code was gone. Clearly we would like people using the newer logic that still remains and would be more easily switched to using the code where ever it is in the new repos. I was just questioning the value of doing what we would normally have done given that we will deprecate the whole of Aqua. If you were reading what I meant the same way, then its certainly less work to leave the old deprecated code there, and I was leaning that way as you can see from my earlier comment.
